Set animation's CLIP parameters?

Hello everyone. I'm making UI animations right now and i was wondering if there is any way to set a clip anymations' parameters. Note that i'm not referring to the ones used by animators, for example, to trigger an animation, but the proprieties itelf of the curves of the clip of the object animated

I'll explain better: let's suppose that i have a menu that in 0.15 seconds scales itelf from 0 to, let's say, 10. To do so i just create a new animation clip and add a new curve for the scale. Then i do just adjust it making at time 0 a keyframe with the scale set at 0 and at 0.15 another keyframe with the scale set at 10.

So the question is: is there any way so can i set that "10" at time 0.15 by script without using stuff such as arrays of Keyframes?

Many thanks in advance. Regards asduffo.
